What stands out
Owners have filed 37 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 11 model years of Kia Soul in our records for brakes problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: Do not buy a 2011 Kia Soul without verifying the HECU/brake hydraulic module has been replaced under recall 23V652000 and confirmed working. These vehicles develop serious brake failures, loss of power, and stalling—one burned down completely—and replacement parts were unavailable for years after recall notification.
The bulk of these complaints center on NHTSA recall 23V652000, which addresses a defective hydraulic control electronic unit (HECU) in the brake system. Starting around 80,000 miles and continuing to over 200,000 miles, owners experience the ABS module commanding the brakes to apply without driver input. A vehicle might be cruising at 45–60 mph and suddenly lose power, stall, and refuse to restart for 20+ minutes. Some smell burning plastic afterward. The check engine light and ABS warning lights illuminate. Dealers diagnosed the HECU failure consistently but couldn't repair it—Kia did not have replacement parts available, leaving owners stuck with unrepaired vehicles they were advised not to drive.
One unconfirmed allegation claims a 2011 Soul caught fire and burned completely while parked overnight, destroying the vehicle and damaging a nearby house and shop.
Beyond the HECU problem, owners report brake vibration and grinding sounds, especially during hard stops. One mechanic found brake pad delamination, with fragments interfering with wheel rotation. One owner experienced sudden unintended acceleration while parking, followed by unresponsive brakes; another reports the brake pedal causing the engine to stall. A fourth complaint documents a brake fluid leak from the ABS module itself.
A recall repair backlog that lasted years created a safety exposure: owners drove vehicles known to have life-threatening brake failures with no remedy available.

Failure modes owners describe
Hydraulic Control Electronic Unit (HECU) failure causing loss of braking and drivability
The ABS/HECU module fails, resulting in loss of braking response, unintended braking, stalling, power loss, and inability to restart. Owners report the module continuing to draw power even when the vehicle is off, and smell burning plastic or abnormal smoke. This is the core failure underlying recall 23V652000.
When: 80,000 to 200,000 miles
Symptoms owners cite: Vehicle applies brakes without driver input while driving; Vehicle stalls or loses power while driving; Vehicle will not restart immediately, requires 20+ minutes before restart possible; Traction control warning light illuminated; Check engine/MIL warning light illuminated; ABS warning light illuminated; Electronic stability control warning light illuminated; TPMS warning light illuminated; Burning plastic odor; Abnormal smoke odor from engine compartment; ABS module running while vehicle is turned off (drawing battery); Failure to respond to accelerator pedal
Repairs/costs cited: Recall 23V652000 parts unavailable as of complaint dates. Some owners had HECU diagnosed by dealer but not repaired due to part unavailability. One owner attempted independent repair with camshaft and crankshaft sensor replacement and spark plug replacement without resolving the issue.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V652000 (Service Brakes, Hydraulic); however, replacement parts were not available at the time of complaints. Dealer advised some owners not to drive the vehicle.
Brake vibration and grinding sensation
Owners report severe vibration, grinding, or knocking sounds when braking, especially during emergency stops. Dealer reports indicate brake pad delamination and emergency brake shoe wear. Some owners experience rattle in the rear quadrant that diminishes with light braking.
When: Mileage not specified in narratives
Symptoms owners cite: Vibration that increases then decreases in frequency during braking; Grinding-like vibration noise under vehicle during braking; Sound described as hard rocks or gravel on brake pads; Loud knocking or rattle from right rear quadrant; Jerking sensation while braking; Brake pad delamination
Repairs/costs cited: Dealer replaced emergency brake shoe. Brake pad delamination found; dealer indicated delaminated pad fragments caused vibration by interfering with wheel rotation during subsequent revolutions.
ABS hydraulic fluid leak from ABS module
Owner observed brake fluid spotting on driveway. Independent mechanic diagnosed leak originating from the ABS system and linked it to recall 23V652000. Dealer disputed whether VIN was included in recall and did not repair.
When: 128,000 miles
Symptoms owners cite: Oil/brake fluid spots on driveway; Leak from ABS system
Repairs/costs cited: Independent mechanic identified leak from ABS system; repair not performed due to recall part availability and VIN exclusion dispute.
Recalls/TSBs owners mention: Recall 23V652000 referenced; dealer stated VIN not included in recall coverage.
Engine fire originating in engine bay
Vehicle caught fire and completely burned while parked overnight. Fire originated in the front engine bay and spread to engulf entire vehicle. Owner believes recall 23V652000 was responsible. Vehicle was a total loss; nearby house, motorcycle, and shop sustained damage.
When: 165,000 miles
Symptoms owners cite: Vehicle caught fire in engine bay while parked; Fire spread to entire vehicle; No warning lights prior to fire
Repairs/costs cited: Vehicle destroyed by fire. Fire department and police reports filed.
Recalls/TSBs owners mention: Owner suspected NHTSA campaign number 23V652000 (SERVICE BRAKES, HYDRAULIC) caused the failure.
Vehicle acceleration failure and loss of braking
In one incident, vehicle accelerated unexpectedly when driver pulled into a parking space, brakes went unresponsive, and vehicle went over a parking curb onto a walkway. Owner struck corner of store which stopped the vehicle.
When: Mileage not specified
Symptoms owners cite: Sudden unintended acceleration while parking; Brakes went to floor (unresponsive)
Brake pedal engagement causing stalling and no-start condition
Pressing the brake pedal causes the engine to stall. Additionally, vehicle will not start when fueling up. Dealer diagnostic work identified evaporative emission control issues but the core brake-stall relationship remains unresolved.
When: Mileage not specified
Symptoms owners cite: Engine stalls when brake pedal is pressed; Vehicle will not start after fueling; Evap leak detected; Fuel malfunction; Canister solenoid issue
Repairs/costs cited: Owner paid $480 to repair evap canister purge vent, evap leak, fuel malfunction, and canister solenoid issues; brake-stall problem may persist.
